Watch: Monster bridge-building machine in China

Check out this wild Tech Insider video we just came across of a monster bridge-building machine in China. The Segmental Bridge Launching Machine, known as the SLJ/32, seemingly constructs bridges in midair. The machine is loaded with prefabbed sections of the bridge. Then it rolls over and past an already installed section of the bridge on a track so it can put the next section into place.
